Question : I recently received a query from an application owner, who reported application outage issue.
An inspection of the db2diag.log file found this message. How can I solve this problem?
DIA3208E Error encountered in TCP/IP protocol support. TCP/IP function "close". Socket was "3". Errno was "9". Errno was "9".
